Description

The actuating device on car that is used for vertical lift

Technical field

The present invention relates to a kind of actuating device on lift car that is used for vertical lift as described in the preamble as claimed in claim 1.

Background technology

The actuating device of using by the described type elevator of the known beginning of EP 0 684 204 A2 for example.This known actuating device is installed on the lift car and comprises that two have drive wheel respectively respectively by a motor-driven axle on its end, and each drive wheel rolls on the track of lift car both sides in special use.The shortcoming of this known structure mainly is, for power is delivered on the track, sometimes must apply very big moment, this is related to very big retarder, has only with very big drive wheel (thereby must have very big gap) and custom-designed for this reason I shape slide rail (Doppel-T-Laufschiene) and could realize.Therefore employed drive motor is also had higher requirement, this causes elevator can reach 100% (that is to say the light mass of counterweight=car) at most in the design aspect its weight and the counterweight again.

Summary of the invention

Therefore the objective of the invention is, a kind of actuating device that is used for vertical lift is proposed, it does not have above-mentioned shortcoming and especially can realize 150% design (that is to say, the light mass+workload of counterweight=lift car 1/2) and can use commercial elevator rail commonly used (frame mode that has groove and spring).

This purpose realizes by the feature of claim 1.

Other favourable embodiment is drawn by dependent claims.

Have two supports by geometry of the present invention, its upper support is provided with the axle of pulley.A support is connected with drafting tool, and another support is connected with car through two tracks, and two supports interconnect by the parallelogram guide rod.This annexation make a described support by the drag load that applies by counterweight and drafting tool towards the top tractive.Simultaneously, these supports load towards the below and therefore press mutually by the gravity of car.Therefore, with each support bonded assembly axle on pulley always rub and abut on the corresponding slide rail sealedly.In addition, both made under lasting situation about using, the friction of pulley and slide rail is sealed can not to be worsened yet.Therefore only in addition, have littler driven roller with respect to prior art, need apply littler power and moment, 150% the design that this has reduced the gap in littler retarder and therefore can realize elevator generally by actuating device of the present invention.

Can use commercial moulding orbit commonly used, entire mechanism designs to such an extent that conserve space, price are favourable.

Description of drawings

Explain the present invention in detail by Fig. 1 to 3 below.

Fig. 1 has the section drawing of the vertical lift of actuating device of the present invention,

The block diagram of two supports of Fig. 2,

The block diagram of two supports of Fig. 3 under the stack-mounted profile.

The specific embodiment

Fig. 1 shows a vertical lift, has a car K who has been equipped with actuating device of the present invention.Car K by two supports 1.1 and 1.2 and drafting tool Z for example steel cable be connected with a counterweight G.Slide rail S (only showing one) is arranged on the both sides of car K, is installed in pulley on support 1.1 and 1.2, that drive by motor 10.1,10.2,11.1,11.2 and rolls on slide rail.

Sealed in order to improve friction when this rolling movement, guarantee especially that therefore pulley keeps excellent contact with slide rail at any time, is provided with two supports 1.1 and 1.2 by the present invention, as shown in Figure 2.

Each support 1.1,1.2 has the basic structure of an essentially rectangular, supports two axles 5.1,6.1 and 5.2,6.2 on it respectively.Each root axle 5.1,5.2,6.1,6.2 has and is not arranged on the drive wheel 9.1,9.2 that is used on its free end 7.1,7.2,8.1,8.2 with slide rail interlocking rotatably.Every axle 5.1,5.2,6.1,6.2 drives by a motor 10.1,10.2,11.1,11.2, and wherein, each motor 10.1,10.2,11.1,11.2 is more preferably with the reducing motor of its electrical axis about the transporting direction on even keel setting of elevator.Be provided with a mechanism 4 in order to be connected with drafting tool Z.For support 1.1 and 1.2 be connected, Connection Element 16.1,17.1 is hinged on each root axle 5.1,5.2,6.1,6.2 on first support 1.1, and described Connection Element can connect into parallel guide rod 16,17 (see figure 3)s with the Connection Element 16.2,17.2 that is located at respectively on described another support 1.2.

Preferably on its contact surface, have a groove at the Connection Element of describing below Fig. 2 17.1,17.2, before Connection Element connects into guide rod, be used for to be inserted in this groove with the part of support 1.1,1.2 and car K bonded assembly bindiny mechanism 12.

Fig. 3 shows two stack-mounted supports 1.1,1.2 at last.Each support 1.1,1.2 has the basic configuration of the rectangle that constitutes by lateral parts 2.1,2.2,3.1,3.2.Constitute parallelogram guide rod 16 and 17 by the Connection Element of preferably tightening mutually by bolt.A described support 1.1 is applied drag load by a bindiny mechanism 4 by counterweight G and drafting tool Z in use.By being connected of first and second supports 1.1 and 1.2 hinged and the parallelogram guide rod by the bottom and bindiny mechanism 12 (see figure 2)s, these two supports 1.1 and 1.2 are pressed mutually.Therefore move relative to each other with axle 5.1,5.2 and 6.1,6.2 bonded assembly drive wheels 9.1,9.2 and therefore can tightly abut on the slide rail.

Drive wheel 9.1 and 9.2 and the friction of slide rail is sealed so realized that by means of support 1.1 and 1.2 of the present invention these supports move relative to each other through parallelogram guide rod 16 and 17 by the gravity of counterweight G and car K.Therefore especially can realize, both make and do not reduce also under the situation of using vertical lift for a long time that friction lock merges and pulley can always roll equably on slide rail.
